Embodiment 1

[0021] Example 1, such as figure 1 The middle waterproof layer 2 is pasted on the inner surface of the outer protective shell 1, and the connection mode between the outer protective shell 1 and the inner protective shell 3 is a screw connection, which plays a good role in moisture-proof, keeps the motor body 7 dry, and prevents water damage , the first springs 4 are equidistantly arranged between the inner protective case 3 and the heat-absorbing box 5, and the connection mode between the heat-absorbing box 5 and the motor body 7 is a snap connection, and the connection mode between the heat-absorbing box 5 and the dustproof plate 6 For welding, and the longitudinal section of the dust-proof plate 6 is a circular arc-shaped structure, which prevents the motor body 7 from being damaged due to the back and forth shaking of the bumpy road section, and has a good buffering effect, and the heat-absorbing box 5 can absorb the heat produced by the motor body 7 when it is working. A l...

Embodiment 2

[0022] Example 2, such as image 3 There are two movable rods 13 arranged symmetrically with respect to the mounting block 10, and the movable rods 13 are mutually intersected with respect to the rotating block 12. The movable rod 13 is a rotating structure on the mounting block 10, and the upper end of the movable rod 13 is connected with the second spring 14 The outer surface of the lower end of the mounting block 10 is connected, through the action of the movable rod 13 and the second spring 14, it is convenient to quickly connect the heat absorbing box 5 with the inner protective shell 3, and it is also convenient to separate the two through the action of the push block 16, which is convenient. The maintenance work of the staff in the later period can also clean up the interior.

[0023] Working principle: When using the installation structure of the middle motor of the electric bicycle, firstly, the motor body 7 is snapped inside the heat-absorbing box 5, and the rotating...

Abstract

The invention discloses an installation structure of a central motor of an electric bicycle. The installation structure comprises an outer protection shell, a rotary block and a first gear plate; a waterproof layer is arranged on the inside surface of the outer protection shell; a first spring is arranged on the inside surface of an inner protection shell; a dustproof plate is installed on the topof a heat absorption box; a rotating shaft is connected to the lower end of the motor body; furthermore, a sleeving shell is arranged on the outside surface of the rotating shaft; an installation block is arranged at the bottom of the heat absorption box; the rotary block is positioned at the bottom of the installation block; a second spring is installed on a movable rod; furthermore, an installation cylinder is arranged outside the movable rod; a pushing block is arranged in the lower end of the installation cylinder; the first gear plate is positioned at the lower end of the rotating shaft;and furthermore, a second gear plate is arranged at the left side of the first gear plate. The installation structure of the central motor of the electric bicycle disclosed by the invention is convenient to disassemble and install, and provided with a heat dissipation device and a buffer device; the protection device is relatively perfect; the waterproof performance is better; and, due to arrangement of the dustproof plate, dust difficultly enters the motor.

Description

technical field [0001] The invention relates to the technical field related to electric bicycles, in particular to a mounting structure for a central motor of an electric bicycle. Background technique [0002] With the popularity of electric bicycles, their overall structural design and transmission system structure have also been greatly developed. Compared with the traditional front drive and rear drive, the mid-mounted motor has been widely used due to its advantages of low reluctance, labor saving, small size, light weight, large torque suitable for climbing, and convenient installation and maintenance. Application, the installation structure of the middle motor of the general electric bicycle is inconvenient to disassemble and install, there is no heat dissipation device and buffer device, the protection device is not perfect, the waterproof performance is poor, and the inside of the motor is easy to enter dust, which is not convenient to clean. Therefore, we propose an...
